Number of hits while crawling a website...?


Number of hits while crawling a website...?

To fix this issue If you download an entire page from a site with urllib, it will account as one (1) hit.
Save the page into a variable, and work with this variable from now on.

Does that help You can add them to an existing URLPool. The existing URLPool implementations are not expandable so you have to create your own URLPool class that is expandable. I called my class ExpandableURLPool.
The URLPool.setProcessed method is called by the framework upon completion of processing and it is there you can add additional URLS to the url list. I will follow with an example, but first, the URLPool documentation states:
code :
class ExpandableURLPool implements URLPool {
List<String> urlList = new ArrayList<String>();
int cursor = 0;

int outstandingQueryies = 0;

public ExpandableURLPool(Collection<String> seedURLS) {
    urlList.addAll(seedURLS);
}

@Override
public boolean hasNextQuery() {
   return  cursor < urlList.size() || outstandingQueryies > 0;

}

@Override
public Query getNextQuery() throws URLPoolException {
    try {
        if (cursor >= urlList.size()) {
            return null;
        } else {
            outstandingQueryies++;
            return new Query( urlList.get(cursor++) ) ;
        }
    } catch (MalformedURLException e) {
        throw new URLPoolException( "invalid url", e ) ;
    }    
}

@Override
public void setProcessed(Query query) {
    outstandingQueryies--;


}

public void addURL(String url) {
    urlList.add(url);
}

}
    class MyWorker extends org.niocchi.gc.DiskSaveWorker {

    Crawler mCrawler = null;
    ExpandableURLPool pool = null;

    int maxepansion = 10;

    public MyWorker(Crawler crawler, String savePath, ExpandableURLPool aPool) {
        super(crawler, savePath);
        mCrawler = crawler;
        pool = aPool;
    }

    @Override
    public void processResource(Query query) {
        super.processResource(query);
        // The following is a test
        if (--maxepansion >= 0  ) {
            pool.addURL("http://www.somewhere.com");
        }       

    }


}

around this issue This is a known issue. Once you operate on a HIT via the API, the batch interface no long works correctly.
The Manage HITs Individually page should still be updated correctly, though.

I think the issue was by ths following , When I need to scrap a website I normally:
1 - Navigate the target website on a normal browser (ff, chrome, etc.), while monitoring/logging any POST/GET requests containing pertinent info via Developer Tools -> Network Tab.
code :
$headers = [
    "Connection: keep-alive",
    "Accept: application/json, text/javascript, */*; q=0.01",
    "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36",
    "DNT: 1",
    "Accept-Language: pt,en-US;q=0.9,en;q=0.8,pt-PT;q=0.7,pt-BR;q=0.6",
];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://s1te.com/json_rand.php");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$server_output = curl_exec ($ch);
curl_close ($ch);
print  $server_output ;
from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()

I hope this helps you . ping is a network command not using the port 80 or http protocol. So there's no way it can count towards a rails application hit.
